nope, I do not sale just brackets, the pedal to master alignment is critical for these to work properly, back when i did waste precious 6061 aluminum selling brackets, only 2 confirmed successes out of 6,
i must have the exact parts to align it properly, each and every set is custom fitted according to the pedal extension angle, and although i use a semi-primitive jig, and they are close, each one is slightly different, and it's enuf to throw everything off
fabbing the brackets are what take most of my time, and for me to charge for that time, you're better off just sending me the gsxr parts and your brake pedal, i fab and assemble everything and send you back a complete, fully assembled, bolt on and ride kit
it's the only way i do it anymore
PM me if interested
your other option is to go into my albums and look at the pics of my systems and fab your own
